3 Ways to Convert Python App into APK When you write an android app with python (see how to), with packages like kivy, it is suffering that convert your Python code into installable/runable APK file for real mobile Android devices. This blog is borrowing Kaustubh Gupta’s blog and is re-edited to introduce the 3 ways to obtain the APK from Python Android app code. 1. The challege we need to package the python code properly, otherwise, Python apps build with Kivy cannot be directly transferred to android devices.

Custom IPython Jupyter Notebook keyboard shortcut to duplicate current line in edit mode For Microsoft Windows User (pcDefault) Create a new JS file under ~/.jupyter/custom/custom.js if it does not exist, and add the next code: /** * * Duplicate a current line in the Jupyter Notebook * Used only CodeMirror API - https://codemirror.net * **/ CodeMirror.keyMap.pcDefault["Ctrl-Down"] = function(cm){ // get a position of a current cursor in a current cell var current_cursor = cm.doc.getCursor(); // read a content from a line where is the current cursor var line_content = cm.

1. Load data and get to know the meta data import pydicom raw_medical_image = pydicom.read_file(file_path) print(raw_medical_image) medical_image = raw_medical_image.pixel_array plt.imshow(medical_image, cmap='gray') # cmap -- color map 2. Five steps of processing 2.1 Transforming to HU: obtain the HU by using Rescale_Intercept and Rescale_Slope headers: hu_image = image * medical_image.RescaleSlope + medical_image.RescaleIntercept #window_image: img_min = window_center - window_width // 2 img_max = window_center + window_width // 2 window_image = image.copy() window_image[window_image < img_min] = img_min window_image[window_image > img_max] = img_max 2.2 Removing Noises segmentation = morphology.

基于pycomm3包的Ethernet/IP协议的python实现 Ethernet/IP(EIP)协议的通信python实现，用pycomm3包进行支持。 Ethernet/IP 协议可能要求包含的功能：隐式报文通信、显示报文通信 (Explicit 讯息通信)、支持UCMM 及Class3 如果您需要创建Ethernet/IP协议的自定义实现，则通常需要研究Ethernet/IP规范、处理低级套接字通信、消息编码和解码、消息的组装和拆解以及各种其他特定于协议的细节。这是一项复杂的任务，需要对网络协议和编程有扎实的理解。在大多数情况下，建议使用现有的库或工具来节省时间并确保可靠的通信。 Ethernet/IP 协议的从头实现比较复杂，但是也有相关的库可以调用。比如 python 的 pycomm3。 pycomm3库抽象了许多Ethernet/IP协议的复杂性，但是了解协议的概念和结构对于有效地使用库并排除可能出现的任何问题仍然很重要。 Here’s a basic example of how you might use it to communicate with an Ethernet/IP device: $ pip install pycomm3 #====== python通信代码：========= from pycomm3 import LogixDriver # Create a LogixDriver instance with LogixDriver('192.168.1.100') as plc: # replace '192.168.1.100' with the actual IP address of your device # Read tag values tag_values = plc.read('Tag1', 'Tag2') # adjust the tag names and values as needed # Write tag values plc.

Below is installing and creating a hugo site with theme=fluency with operations like: hugo new site sonictl.github.io cd sonictl.github.io git submodule add https://github.com/wayjam/hugo-theme-fluency.git themes/fluency echo "theme = 'fluency'" >> hugo.toml hugo server by following this https://gohugo.io/getting-started/quick-start/ add blog content: **directly add a .md file in content/posts ** or ask hugo to creat one post: hugo new posts/my-first-post.md this create a new file under content/posts Note the draft value in the front matter of your post. if its value == true, You can run either of the following commands to include draft content.

Sumerizing: The ways and implementations for assigning wifi passcode to ESP32/ESP8266 MCU Assigning WiFi pass code to ESP chip is ubiqutous. To summerize, we can do it with ways listed below: AP mode: A web running on chip, Chip working as Station mode. Bluethooth. (ESP8266 has no bluetooth moduel.) ESP Touch App with ESP smartConfig© solution. (5G Hz is not supported.) others, such as AP-STA link by routers, AP by cellphone, wifi manag-frame broadcasting.

Let me share some thoughts bout creating academic research paper. How to find the innovative ideas for a new paper A new idea is believed by the newbee PhD student a precious seed for his/her paper. And the papers are believed as their lifesaver for their tough days. Solution: a. adjust the mindset. A book named as ‘phD grind’ written by Philip Guo may helps. b. In your research area, hack up a classical work, a hot research work, a gorgeous work or a work you just want to hack up.

How to use LittleFS on ESP32 with vsCode+platfromIO As a suplement of this tutorial How to use LittleFS on ESP8266 I follows some reference and examples to build this blog. Get to konw some basic introductions about SPIFFS and LittleFS on ESP8266 and ESP32 is necessary for a noob. Note: Most of the functions for SPIFFS operations are compatible for LittleFS. follow the tutorials one by one: - SPIFFS for ESP8266 - SPIFFS for ESP32 - LittleFS for ESP8266 - LittleFS for ESP32 LittleFS is newly introduced into ESP32 SDK (Aug 2021) .
